Junk food!

Pizza in Japan is not at all like pizza in Sweden (though both are good). In Japan, pizza is considered some form of luxury food. Probably the thinking is: pizza is Italian, Italian food is the world's greatest (or number two, fighting with French cuisine) and very high class and expensive, thus pizza must be luxury food and expensive.

In Sweden, pizza is considered junk food and is one of the few things you can eat without paying half your salary. And for some reason pizza in Sweden always comes with shredded cabbage.
